Old games on Steam functioning as virus vectors?

[Gobermental Supervisor]

One doesn't have to remove the game from the steam library of those who purchased it, rather they could just stop selling it

And because they ARE selling it they should be held liable by the state for distributing malware.
This is absolutely ridiculous. This should not be a consumer protection thing, this should be a criminal investigation into a games company selling software with a known vulnerability, which is comparable to selling malware.
